Experience of The First 12 Weeks of Pregnancy: 1st Trimester

 

Experience of The First 12 Weeks of Pregnancy: 1st Trimester

The average gestational age is forty weeks; however, the embryo's time in the womb is limited to roughly 38 weeks. This is so because a pregnancy is measured starting on the first day of the last menstrual cycle for the woman, rather than the conception date, which usually happens two weeks later. By sharing your pregnancy experience of the 1st trimester you can submit a guest post on health.

Trimesters, or roughly three months each, are the three phases into which pregnancy is divided:

  • First Trimester – Conception to 12 weeks
  • Second Trimester – 13 to 27 weeks
  • Third Trimester – 28 to 40 weeks

A Detailed Summary of First Trimester – Conception to 12 Weeks

Conception

When the man's sperm fertilises the woman's ovum (egg), that is when conception occurs. At that moment, the gender and hereditary traits are determined.

Pregnancy Week 1

Your menstrual period is starting this first week. This week counts towards your 40-week pregnancy even though your baby hasn't been conceived yet since your expected birth date, also known as your due date or EDB, is calculated commencing with the first day of your last menstrual cycle. Your due date can be found using a gestation calculator if you know when your last menstrual cycle occurred.

Pregnancy Week 2

Conception, the process by which the sperm fertilises your egg, will happen sometime this week.

Pregnancy Week 3

The cell divides in half thirty hours after fertilisation. The zygote is now in the uterus (womb) after migrating from the fallopian tube after two more days. The zygote burrows into the fat uterine lining (endometrium) seven days after conception. The term "blastocyst" now refers to the zygote.

Pregnancy Week 4

The growing child is smaller than a rice grain. The digestive system is one of the many bodily systems that are formed by quickly dividing cells.

Pregnancy Week 5

In the end, the central nervous system which includes the brain and spinal cord will develop from the neural tube.

Pregnancy Week 6

The infant is now referred to as an embryo. It is around 3 mm long. At this point, it is secreting certain hormones that stop the mother's menstruation from occurring.

Pregnancy Week 7

The heart is pumping. The amniotic sac and placenta have fully grown in the embryo. The placenta digs into the wall of the uterus to obtain nutrients and oxygen from the mother's blood.

Pregnancy Week 8

At this point, the embryo's length is about 1.3 cm. The spinal cord resembles a tail due to its fast growth.

Pregnancy Week 9

The tongue, lips, and eyes are developing. The embryo can begin to move around thanks to its tiny muscles. In the embryo, the liver creates blood cells.

Pregnancy Week 10

The embryo, which is roughly 2.5 cm long, is now referred to as a foetus. Every organ in the body is formed. The hands and feet are changing into fingers and toes from what they were before nubs or paddles. Brain waves are indicative of an active brain.

Pregnancy Week 11

Teeth are erupting from beneath the gums. The small heart continues to grow.

Pregnancy Week 12

Though still joined by skin webs, the fingers and toes are identifiable. Around this time, a combined screening test for the first trimester (a maternal blood test with a baby ultrasound) can be performed. Trisomy 18 (Edward syndrome) and trisomy 21 (Down syndrome) are detected by this test.
